                     class, this variable identifies packages that contain fonts
                     the OpenEmbedded build system installs.
-                    By default, installed fonts appear in the main package
+                    By default, the <filename>fontcache</filename> class assumes
+                    that fonts appear in the main package
                     (i.e. <filename>${</filename><link linkend='var-PN'><filename>PN</filename></link><filename>}</filename>).
                     Use this variable if fonts you need appear in a package
                     other than that main package.
